This document outlines the five major perspectives in psychology: biopsychological, psychodynamic, behavioral, cognitive, and humanistic. It provides a brief overview of each perspective, including their key theorists and focuses. The biopsychological perspective studies biological bases of behavior like genes and brain chemistry. The psychodynamic perspective emphasizes unconscious drives and childhood experiences. Behaviorism only considers observable behaviors and environmental influences. Cognitive psychology focuses on internal mental processes like problem-solving and memory. Finally, humanism views people as inherently good and focused on self-actualization.
